- DROP ROLE [ IF EXISTS ] <em class="replaceable"><code>name</code></em> [, ...]
- </pre></div><div class="refsect1" id="id-1.9.3.126.5"><h2>Description</h2><p>
- <code class="command">DROP ROLE</code> removes the specified role(s).
- To drop a superuser role, you must be a superuser yourself;
- to drop non-superuser roles, you must have <code class="literal">CREATEROLE</code>
- privilege.
- </p><p>
- A role cannot be removed if it is still referenced in any database
- of the cluster; an error will be raised if so. Before dropping the role,
- you must drop all the objects it owns (or reassign their ownership)
- and revoke any privileges the role has been granted on other objects.
- The <a class="xref" href="sql-reassign-owned.html" title="REASSIGN OWNED"><span class="refentrytitle">REASSIGN OWNED</span></a> and <a class="xref" href="sql-drop-owned.html" title="DROP OWNED"><span class="refentrytitle">DROP OWNED</span></a>
- commands can be useful for this purpose; see <a class="xref" href="role-removal.html" title="21.4. Dropping Roles">Section 21.4</a>
- for more discussion.
- </p><p>
- However, it is not necessary to remove role memberships involving
- the role; <code class="command">DROP ROLE</code> automatically revokes any memberships
- of the target role in other roles, and of other roles in the target role.
- The other roles are not dropped nor otherwise affected.

- <span class="productname">PostgreSQL</span> includes a program <a class="xref" href="app-dropuser.html" title="dropuser"><span class="refentrytitle"><span class="application">dropuser</span></span></a> that has the
- same functionality as this command (in fact, it calls this command)
- but can be run from the command shell.
- </p></div><div class="refsect1" id="id-1.9.3.126.8"><h2>Examples</h2><p>
- To drop a role:
- </p><pre class="programlisting">
- DROP ROLE jonathan;
- </pre></div><div class="refsect1" id="id-1.9.3.126.9"><h2>Compatibility</h2><p>
- The SQL standard defines <code class="command">DROP ROLE</code>, but it allows
- only one role to be dropped at a time, and it specifies different
- privilege requirements than <span class="productname">PostgreSQL</span> uses.
